Before coming, Cheng Wushuang had already 'touched' the method of the construction of the instrument city in the art of refining, and the fact that others could not repair the 'jade' of the core did not mean that he couldn't. , the latest chapter access: ШШШ.79xs.СоМ .

You must know that the Heavenly Demon Ark of the Heavenly Demon Clan is actually a appliance city, but the structure of this kind of appliance city is very complex, belonging to the god level and even the ancestral class, which contains a large number of space laws, although Cheng Wushuang understands, but can only understand the theory, for the power of space laws, he can't 'intervene'.

However, the black city in front of him is different, the black city is just made of some rare spiritual iron, and the spiritual power veins engraved are the simplest and most basic spiritual power veins, not only that, but even the 'essence' spirit engraving and spiritual power engraving engraved on the core 'jade' are very ordinary.

Repairing the 'jade' of the core and branding the entire black city with a new 'spirit' spirit seal is a very simple matter for Cheng Wushuang.

Walking into the 'jade' of the core, Cheng Wushuang took out a very pure spirit stone, which was not obtained by himself, but was found from those enemies who had been killed.

Seeing Cheng Wushuang take out a spirit stone that exuded a strong force, Murong Zhi's face changed, and he immediately exclaimed: "Brother Wushuang, you won't want to repair the 'jade' of the core, right?"

Cheng Wushuang nodded and said, "Yes, the purpose of my coming here is indeed to repair the 'jade' of the core, and this parchment scroll is what I got at a high price, in order to find the hidden tunnel leading to the 'jade' of the core." ”

Cheng Wushuang didn't hide anything, and said the purpose of coming here.

Hearing this, Murong Qiong and Murong Zhi's faces changed slightly, their eyes flickered, and from their expressions, a trace of shock could be seen.

Murong Zhi took a breath, although he heard that Cheng Wushuang was supernatural in alchemy, and he also knew the art of refining, but if he wanted to repair the 'jade' of the core and make the entire black city a new one, even if he was a saint-level refiner, he was probably not completely sure.

After all, the Black City is a product of ancient times, and there is a huge gap between it and today's ancient times.

In the process of repairing the 'jade' of the core, the slightest carelessness will destroy the 'jade' of the entire core, and at that time, this black city will really become a ruined city.

At that time, the formation in the black city will also be in an instant, and the countless warriors in the black city will all suffer, and the current time should be the time point when the demon beast 'tide' broke out, and if you go on a business trip at this point in time, the consequences will be very serious.

Murong Zhi immediately said in a deep voice: "Brother Wushuang, don't you repair the 'jade' of the core at will, although you are good at alchemy, but this alchemy technique is also quite mysterious, just take this appliance city as an example, the structure is complicated, with your current ability, if you let this core 'jade' be broken, then the black city will be completely finished." ”

"Even that formation will disappear. ”

Although Murong Zhi's tone was a little serious, everything was sincere, without any malice and contempt for Cheng Wushuang.

In his eyes, Cheng Wushuang can be regarded as a genius, and those who have the method of external refining have a great status in the Danta, even if they only have the cultivation of the Realm Spirit Realm, some Immortal Feather Realm martial artists must respect this person.

But Murong Zhi couldn't believe that Cheng Wushuang was also profoundly accomplished in the art of alchemy, even more advanced than the art of alchemy.

Murong Qiong also had the same idea as Murong Zhi, he felt that Cheng Wushuang's idea was not bad, but he should do what he could, many refiners had some ideas about the Black City, but it was just an idea, no one repaired it, as long as one was not careful, the Black City would cease to exist, and then the entire city would be exposed to the vision of the demon beasts.

"Don't worry!"

"Give me half an hour, and you'll be done. ”

From the words and expressions of the two, Cheng Wushuang already knew that they couldn't believe that he had the strength to repair the core 'jade', but he wasn't angry, after all, it was very difficult for ordinary refiners to understand this kind of thing.

In his mind, all that was recorded was the knowledge of the ancient level of refining weapons, and the level of profundity, the ancient level of the instrument city, even if it was a piece of cake in front of him, if it wasn't for his lack of strength, he could have created the instrument city by himself.

Cheng Wushuang suddenly 'revealed' a confident smile.

Murong Qiong and Murong Zhi originally planned to stop Cheng Wushuang, but when they saw Cheng Wushuang's faint confident smile, they dispelled this idea again, and said in a trance: Maybe this young man can really do.

Murong Qiong thought of the amazing combat power that Cheng Wushuang showed when he killed Zhang Chen and the others with the power of one person before, and heard that Cheng Wushuang had just entered the Black City, and he had successively killed the three great Tianjiao of the White Pavilion Dynasty, and learned that Cheng Wushuang was actually the young powerhouse in the Battle of the Barren Mountain, and he had obtained the inheritance of the ancient top sect 'gate' such as the Nine Seal Sect.

"Maybe he can really repair the 'jade' of the core!"

Murong Qiong said secretly, reminding herself that she should believe in Cheng Wushuang, after all, this young man is a genius monster, and he should not be viewed with common sense.

Murong Zhi didn't know what to say because Cheng Wushuang had saved him, but just prayed that Cheng Wushuang would never poke any basket.

At this moment, Cheng Wushuang had already concluded the first 'essence' spirit seal and spiritual power seal.

An ancient and mysterious power 'wave' emanated from the two inscriptions, causing Murong Zhi's eyes to widen suddenly.

Murong Qiong is not a refiner, she can't perceive the subtlety of these two seals, but Murong Zhi is different, as a super-level refiner, he can clearly understand that the laws contained in those seals are very complex, and this level of complexity is the 'wave' of mysterious power that he would only emit when he once watched a great refiner build an ancient-level instrument.

"This is an ancient level mark!"

Murong Zhi exclaimed in surprise, he couldn't imagine that Cheng Wushuang would be able to conclude the Ancient Seal so quickly.

I saw that the 'jade' stone in Cheng Wu's hands, after being injected with two inscriptions, turned into a mass of white 'colored' 'jade' liquid, hovered in the void once, and merged into the core 'jade'.

The 'jade' of the core immediately bloomed with a brilliant light.

Cheng Wushuang didn't stop, and immediately quickly concluded the 'essence' spirit engraving and spiritual power engraving, which were continuously injected into the core 'jade', and he had to cover all the broken carvings in the core 'jade' before he could repair the core 'jade'.

For half an hour, the feeling given to the Murong brothers and sisters was just a blink of an eye, and during this time, Cheng Wushuang had concluded a total of 128 inscriptions, of which 48 were engraved by the 'essence' spirit and 80 were engraved by spiritual power, and the 'jade' of the core was successfully restored perfectly.

With the moment the 'jade' of the core was successfully restored, the entire black city shook.

The warriors who lived in the black city immediately made an uproar, thinking that the beast 'tide' was coming, and they were immediately terrified.

After countless warriors shook violently in the black city for a few breaths, they were shocked to find that a white light appeared in the center of the black city.
